That's because Mercedes' QR code stickers will link to a copy of the car's schematics, so emergency responders can safely see how to save injured occupants in the event of a crash, as explained in the video above.

Already, Germany's regulatory body for automobiles mandates that every car should have a copy of its schematics available, so that rescuers can safely dismantle a crashed car following a major accident. The idea is so that firefighters, paramedics and police don't accidentally cut through a power line or trigger an airbag and so that they know where important parts like the battery and tanks are located.

Mercedes' parent company, Daimler, says it's going to make these "rescue sheets" more readily available by placing two QR code stickers on the car: one behind the fuel door and another on the roof support on the opposite side of its cars. These QR codes can be scanned by a camera-equipped smartphone or tablet to direct emergency personnel to a website with the specific rescue sheet they need to reference. Daimler says they chose these two spots on the car to put the stickers, because "it seldom occurs that both these parts are badly damaged at the same time in an accident, and they are furthermore easily accessible from the outside."

All new Mercedes vehicles will get these special stickers, and the Mercedes QR codes can also be retrofitted for existing cars. The automaker is also waiving its right to patent this idea so that other car companies can implement this sort of technology.
